To all @vhom it may concern:

I '15s it known that I Ls'wls K. Davis, a citizen of the United States, and a'resident of the'city of New York in the county of New York and State'oi New York, .5 United States of America, have invented certain new and useful Improvements in Building Construction, of

which the following is a specification} My inventio'i relates to an improvement in systems of building construction, and its object is to provide a 'epiooi and moisture proof construction for wallslor other structures.

I will describe my in ntion in the following speci iication claims. t r I W Referring tothedrawin'gs, Figure 1 is'a lside elevation of aplate or tile which I use in carrying out my'invention. Fig. 2 is a plan'view of the same.- Fig. 3 is a perand point ou" thefnovel features thereof in spective viewpf-a portion'of a wall or'similar structure 4 made according-to my inventiom with; however,- ,cer-

20. tain of the partsv broken awayxe more clearly show its" construction. Y

Like character's o f reference' designate corresponding parts in in of the figures.

10 designates ari-bbedplate or tile of suitable ma'tek 2i rial, such, for example; as vitrified clay. ,,11', 1 1" designate ri-bs which project" from either side of thistile 10. Tlieyare constructed as clearly shown in Fig. 2 with inwardly flaring sidesj'that is, with their outside width greater than their width at the lines where they join- 3C the plate proper. Thus each of these'ribsis made with undercut edges 12:12 between'which grooves 13, 13 are formed. The tiles 10 are preferably salt-glazed to ren-,

der themimpervious to moisture. By placing the proecting ribs on one side of the plate between the pro- 35 jecting ribs on the opposite side the plate, the tile plate may be made thinand light and yet have considerab le strength. i

-20 designates a portion of awall oi' my struction. A I

ill, 21 designate I-beams of standard form. Y

i 22 designates the body of the wall which is of con crete or similar substance.

novel con-1 l n'constructing a wall according to my invention, a plurality of tile plates'lO are placed edgeto edge.

They may be placed between/light I beams. as shown which will serve to hold the tiles in place and to stiffen 'the'completed wall. The frame-work'for the wall thus formed may then be covered with concrete or other material and allowed to harden. I find that it is oiteii preferable to first construct a form about the I beams' and the tiles for the finished wall and to then pour the concrete in a plastic or semi-liquid condition into this form;- The .'concrete will .be held firmly onto the sides of the tiles becauseiof the projecting ribs of the shape which I have shown which causes both sides ofthe plates to form holding or binding surfaces for the concrete; J

' It may be seen'that the simplicity-oi this construetion makes it a cheap one to install. The tile and its;

.s'upporting beams form sufficient reinforcement for the concrete. to make a comparatively thin wall otc'on-.

sidemble strength.'- The glazed tile within'the wall makes the wall impermeablea'nd thus removesoneofthe objectionable features of concrete walls.-- Easter--- rnay be put overthe concrete surfaces formediasabove. described, or if desired plaster may-,beapplied directly 1- is r b edtiies. v

Oi 'course,-'if desired, the plates 10 may be provided with'flzifingiibs on-on-l'y oneside. 1

i What I claim and desireto se'c'ure'by Letters Patent of the United States is: I Y

Afivall comprising; a plurality of solid thin flat tiles of ceramic material, said tiles having-parallel flaring ribs projecting fromoppositesurfaces of theme, ,the fihs on one surface of the tile being between those on the opposite ssurface of the tile; metallic I-beams receiving the opposite vertical 'edges 01 the tiles befweentheflanges '01. said beams, and a body of concretesurrounding said tiles and beams and forming the outer surfaces of the wall and bind ing the tiles and beams together.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
